“During the flight, the cabin crew became aware that one of the passengers boarded the incorrect flight and notified the pilot,” ANA told RT in a statement. “As part of the airline’s security procedure, the pilot in command decided to return to the originating airport, where the passenger was disembarked.”

American model Chrissy Teigen was on board the flight, and tweeted about the inconvenience. She said the passenger had a United Airlines ticket.

a flying first for me: 4 hours into an 11 hour flight and we are turning around because we have a passenger who isn’t supposed to be on this plane. Why...why do we all gotta go back, I do not know

RT contacted LAX and LAX police for further information. LAX police would not comment on the issue and deferred to the airline.

“ANA is researching the situation currently to determine how the passenger boarded the flight,” the airline said, adding that it would like to apologize to passengers for the inconvenience. “We take great pride providing exemplary customer service, and on this flight we failed to do so,” it said.
